All that is Solid … is a radical blog that seeks to promote a future beyond capital's social universe. "All that is solid melts into air" (Karl Marx and Friedrich Engels, 'The Communist Manifesto', 1848).

The London Anarchist Bookfair is the biggest anarchist event in the country but there’s a lot more to anarchism than books or bookfairs. Saturday also sees the national TUC organised demonstration in London with a big anarchist presence, showing anarchists are part of all workers struggles. But we don’t accept the idea that our problems will be solved for us by Union leaders or politicians.

If revolution breaks out in Hyde Park we’ll be there. If not the Bookfair is 15 minutes away on the central line.

The week after there is a United Friends and Families Campaigns (UFFC) march – for the hundreds who have died in police custody or at the hands of the police. These cases and the UFFC’s resistance remind us again of what state power and policing means for many people. UFFC will be speaking at the Bookfair.

So the Bookfair is a small part of a movement and struggles that become more crucial every year. But it’s also a celebration of those fights and a place to set out our stall(s). As always there are books, magazines and newspapers full of ideas and opinions and passion, there will also be dozens of meetings and discussions, films, cabaret and more than anything a chance to meet other people who want to build a new world.

Anarchism doesn’t mean no organisation, so there’s food, a well-run crèche and older kids space and anything we think can make the day more open and accessible. Crèche Available for children 2-8 years. Younger children welcome with carers. Older children There is a supervised space and a youth space.
